Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a hinge for attaching a toilet bowl cover member (eg, a seat, a toilet lid, etc.) to a toilet bowl.

BACKGROUND OF THE INVENTION A variety of toilet cover butterfly programs are known. The design of such assemblies must take into account the difficulties in cleaning the toilet (particularly around the butterfly top) and the high labor costs involved in assembling the seat to the toilet on the assembly line. Due to these factors, the toilet cover member cannot be easily attached to the toilet.
It is desirable to be able to remove it. Further, it is desirable that such a butterfly programmable member be able to fix the toilet bowl cover member to the toilet bowl without significant loosening of the hinge connection portion, and furthermore, it is desirable that the toilet bowl cover member not be accidentally removed.

Modern toilet designs also place new demands on toilet cover member hinges. That is, as modern toilet bowls have become smaller and more streamlined, the butterfly top must also fit into a smaller space than traditional toilet bowls, and in some cases the toilet lid has to be made higher at the rear. There is a need. Additionally, in some applications, the rear of the toilet seat is substantially downwardly spaced from the toilet lid.

Further, it is desirable that the joint between the toilet bowl cover member and the toilet bowl be hidden and not visible to the user who uses the toilet bowl in a normal position. This hidden joint also helps prevent tampering with the toilet lid, as it is difficult to see how to remove it.

Therefore, the present invention allows the toilet bowl cover member to be easily installed and removed, the connection between the toilet bowl cover member and the toilet bowl is secure and does not come off accidentally, and the joint portion is hidden, and furthermore, the toilet bowl is modern. To provide an improved toilet bowl cover butterfly program that can be used in design.

Means for Solving the Problems The present invention provides a hinge member assembly in which a toilet cover member is attached to the rear of the toilet so as to be rotatable between upper and lower positions around the axis of the hinge, the inner hole being aligned with the axis of the hinge. a hinge shaft element inserted into the bore along the axis of the hinge; one of the elements adapted to be coupled to the back of the toilet bowl; the other of the elements comprising a cover member. furthermore, both elements and the bore are configured to provide a keyed and slotted connection between the elements, such that attachment of the toilet cover member to the toilet requires axial movement of the hinge element. The object of the present invention is to provide a hinged solid body, characterized in that the hinge is inserted into the inner hole along the hinge axis, and the two elements are rotated relative to each other about the axis of the hinge to lock the two elements together. .

With this configuration, the toilet cover member can be assembled and disassembled without excessive loosening at the hinge joint.
and can be easily executed.

In a preferred embodiment, a plurality of hinge receiving elements and hinge shaft elements are provided, each such hinge shaft element being inserted into a corresponding hinge receiving element along the hinge axis. The assembly is designed to move between up and down positions. The toilet bowl cover member passes through the assembly position only momentarily as it is rotated between the upper and lower positions, and it is necessary to apply an axial force at that position to remove the toilet bowl cover member. With this arrangement, the risk of the toilet bowl cover member being accidentally removed from the toilet bowl is minimized.

The invention also provides that in each key-to-slot connection, each bore is keyhole-shaped, and each hinge shaft element extending from the slot along the hinge axis has a radially outwardly extending hole from the hinge shaft element. It is characterized in that a lug is formed that protrudes from the top. The hinge bearing element is held between the lug and the stop in the connected state. A reserve space is also formed in each hinge receiving element to receive a lug corresponding to the hinge element as the hinge element is rotated on the hinge axis. This spare space serves to screen the lug and slot from the user's view and to provide a support surface at the adjacent end of the hinge receiving element.

The invention also provides a pair of hinge shaft elements and a corresponding hinge receiving element. Both hinge axis elements extend in the same direction, and each hinge axis is in a fixed relationship with respect to the other hinge axis. One pair of elements is adapted for connection to the rear of the toilet bowl and the other pair is adapted for connection to the rear of the cover member. The fixed hinge shaft extends far above the toilet bowl and provides a rigid structure for mounting the rear raised toilet lid.

The invention further provides that the base can be fixed to the rear part of the toilet bowl, with the two hinge shaft elements fixed relative to each other on the base. The hinge element is thereby connected to the rear part of the first cover member.

The base may also include a pair of hinge block portions at opposite side ends thereof. Each hinge block portion has a through hole extending from its inner end to its outer end, the through hole being coaxial with a second axis, which is at a lower level than the first axis. The second cover member has a pair of ears formed at the rear and spaced apart to sandwich the hinge block portions with a predetermined spacing between adjacent block portions. each ear has an inwardly opening bore;
This is aligned with the second axis, thereby allowing a pair of hinge pins to be inserted from the hinge block portion into the adjacent ears, thereby axially coupling the second cover member on the toilet bowl. become. Each hinge pin has at least one radially projecting detent that is compressed when passed through the bore and expands within the predetermined space to retain the pin in position. to do. In this regard, the pin is formed with a slot in each locking area so that the pin can be compressed, and the outer end of the pin is formed to extend beyond the outer end of the slot to block it. It is preferable to do so.

The invention also includes a pair of hinge shafts and corresponding hinge elements, each hinge shaft extending outwardly in opposite directions. At least one hinge shaft is axially slidable relative to the other. Once both hinge shaft/hinge element pairs are assembled, the toilet cover and the slidable hinge shaft are attached to the toilet bowl.

In a particularly preferred embodiment relating to this feature, each hinge axis is extendable into a blind hole in an adjacent hinge extension of the second cover member, with the second cover member being axially combined. Therefore, because of this feature, the invention is particularly suited for providing a butterfly stand in which the two toilet bowl cover members are easily attached to and removed from the toilet bowl. This connection can be completely hidden from view by providing the hinge element with a spare space for accommodating the lug of the hinge shaft.

The present invention saves assembly and disassembly time, and at the same time makes handling convenient, compared to the existing three-dimensional toilet cover member. The toilet cover member butterfly assembly according to the present invention can be assembled and disassembled easily and quickly. Furthermore, the butterfly block according to the invention can be constructed very robustly and it is also possible to provide different hinge axes for each of the two different toilet bowl cover parts or the same hinge axis for the two toilet bowl cover parts. A shaft can also be provided and these toilet bowl cover members can be easily removed. Furthermore, the butterfly program object according to the present invention can be hidden from the user's view, thereby preventing the butterfly program object from being tampered with.

The present invention provides a toilet cover member butterfly assembly that can be easily and quickly assembled and disassembled. With the butterfly cover member of the toilet bowl cover member according to the present invention, the butterfly flap portion of the toilet bowl can be easily cleaned. Furthermore, the toilet cover member flap structure according to the present invention is suitable for extending the rear portion of the toilet lid upwardly from the toilet bowl. Furthermore, the three-dimensional toilet cover member according to the present invention can prevent tampering, and there is less risk of the toilet cover member accidentally coming off.

EXAMPLES The advantages and features of the invention described above will become clearer from the detailed description below. The following description will be made with reference to the drawings, which are merely illustrative of preferred embodiments of the invention and are not intended to limit the invention.

1 and 2 are views showing the toilet bowl cover member butterfly program body 10 according to the present invention being attached to the rear part of the toilet bowl 12. As shown in FIG. The toilet bowl 12 is a low, streamlined toilet bowl that slopes downward from a tank portion 13 at the rear toward the front. As can be seen from FIG. 1, the butterfly programmer 10 is not visible to the user in the normal state with the toilet lid lowered. This is an important point in maintaining the characteristic appearance of a streamlined toilet bowl.

Referring to FIG. 3, the butterfly block 10 includes two toilet cover members: a toilet lid 1;
4 and a seat 16. Both lid 14 and seat 16 are hinged to a single hinged base 18 (Figures 4-7). In this preferred embodiment, the hinge base 18 includes a pair of brass shafts 20 and a body 21. The body 21 is formed from a molded material such as plastic. In this case, the hinge shaft 20 is placed in a mold and the base 18 is molded around it. Connect the shaft 20 to the main body 2
Both shafts 20 are permanently fixed to each other by molding in 1 and are firmly fixed for mounting the toilet lid 14 in the raised position.

The hinge shaft 20 is connected to a hole 22 provided at the rear of the toilet bowl 12.
(FIG. 3). The lower end of each shaft 20 further extends from the main body 21 into a hole 22.
A thread is formed through each one of the holes. A pair of nuts 23 are screwed into the ends of the hinge shaft 20 from below the hole 22 to securely fix the base 18 to the toilet bowl 12.

The upper end of each hinge shaft 20 is formed horizontally, and is coaxial with the other hinge shaft 20 on the first axis. A lug 25 is formed near the end of each hinge shaft 20 and projects radially from the hinge shaft. In the preferred embodiment each hinge shaft 2
The angle of inclination of the lug 25 on 0 is made the same as that of the lug 25 on the other hinge axis 20 (both extending downward).

The butterfly body 10 also includes a pair of hinge elements 26 attached to the underside of the lid 14. As shown in FIG. 3, the hinge element 26 is attached to the lid 14 by a dovetail connection, with the sloped sides 27 of the hinge element being fitted into corresponding guideways 28 of the lid 14. The hinge element 26 is then secured to the guideway 28 by adhesive or the like. Alternatively, the hinge element 26 may be molded and formed integrally with the lid 14.

8-11, each hinge element 2
6 has a through hole 28 extending from the insertion end 29 to the locking end 30. Each through hole 28 is keyhole-shaped and has a slot portion 31 and a circular portion 32 to receive the hinge shaft 20, including the lug 25, in the assembled position without undue loosening. The lugs 25 and slots 31 are then aligned with each other. From the lock end 30, there is a preliminary space 3 defined by a bored part 34.
3 extends. Both ends of the bored portion 34 are supported by a bearing surface 37
I will provide a.

When assembling the lid 14 to the base 18, the lid 14 is first aligned with the through hole 28 along the first axis and the corresponding hinge axis 2.
The insertion end 29 is aligned with the insertion end 29 adjacent to both ends of the 0. The slot 31 of the through hole 28 is then inclined so that the shaft 2
0 lug 25 (the lid is aligned with the horizontal plane)
The hinge element 26 (which is at an angle of 45°) is connected to the axis 20
(Fig. 12). As shown in FIG. 13, the hinge shaft 20 is inserted into the hinge element 26 in the axial direction until the insertion end 29 of the hinge element 26 abuts and stops with the stopper means 35 of the main body 21. In this position, each lug 25 passes over the locking end 30 of the corresponding through hole 28 and lies in the reserve space 33.

The lid 14 can then be pivoted up and down and the lugs 25 are brought out of alignment with their respective slots 31, whereby the hinge element 26 is coupled between the stop means 35 and the lugs 25. This also holds the lid 14 in the axial direction relative to the base 18 (FIG. 14). Removal of the lid 14 from the base 18 is accomplished by aligning the slot 31 and the lug 25 to the assembled position of 45 DEG and pulling the lid 14 axially away from the stopper means.

If the lugs 25 and slots 31 are not aligned, the lid 14 is free to rotate about the first axis;
Further, it is fixed to the base 18 along the axial direction. In the preferred embodiment, the assembly device (the angular position where lug 25 and slot 31 are aligned) is between the up and down positions, rather than the up and down positions.
There is therefore little risk of the lid 14 accidentally coming off the toilet bowl as the assembly position is passed only momentarily when the lid is pivoted between the upper and lower positions.

It is also preferred that the two lugs 25 have the same angles with each other, and that the two slots 31 also have the same angles with each other. This allows the hinge shafts 20 to be replaced with each other. It is also preferred that the two hinge axes 20 and the corresponding number of hinge elements 26 have sufficient stability. Of course, depending on the application, only one axis and element may be required, or two or more.
In another variant of the invention, it is also conceivable to fix the hinge shaft 20 to the lid 14 and the hinge element to the base 18.

The present invention provides a toilet cover member butterfly assembly that is easy to manufacture and clean, and allows for quick and easy removal of the toilet cover member. Nevertheless, the butterfly assembly according to the invention is able to provide a secure connection between the toilet bowl cover member and the toilet bowl that cannot be accidentally released. Furthermore, the joint between the hinge shaft and the hinge element is hidden from normal users, improving aesthetics and preventing tampering. This configuration also allows the rear portion of the lid 14 to be formed higher.

Butterfly programmer 10 also connects seat 16 to toilet bowl 12. The seat 16 is hinged to the base 18 for rotation about a second axis between up and down positions. This second axis is parallel to and at a lower height than the first axis.

The base 18 has hinge block portions 40 at each end thereof for hingedly connecting the seat 16. Each hinge block 40 has a through hole 42 in coaxial relationship along a second axis with a through hole 42 in the other portion 40. As can be seen in FIGS. 4 and 7, the inner end of the through hole 42 is located at a recess 43 in the base 18.
It is accessible via. The base 18 has other recesses 45, 4 to save plastic material.
6, 47, and 48 are also provided. A counterbore 50 is also formed adjacent the outer end of the bore 42 . A circular protruding rib 51 is formed around the counterbore 50 to define a preliminary space 52. Projecting rib 5
The outer surface of 1 forms a bearing surface 53.

Stool 16 has a pair of ears 54 adapted to clamp hinge block portion 40. Each ear 54 has a blind hole 55 adapted to be axially aligned with the inwardly opening second axis.

Stool 16 is attached to base 18 using pins 56. Referring to FIGS. 3, 4, 15, and 16, each pin has a head 58 at its inner end and a pair of radially projecting pins spaced axially from the head 58. It has a locking part 60.
The outer end 62 of each pin 56 is spaced a distance from the lock 60 opposite the head 58. A through slot 64 is formed between the locking portions of the pin 56. Since each pin 56 is formed of a flexible plastic material, the presence of the slot 64 allows the pin 56 to be radially compressed in the area adjacent the stop 60. End 62 extends beyond slot 64 to block the outer end of slot 64.

To attach the seat 16 to the base 18, each pin 56 is inserted into one of the through holes 42 from the inside out and into one of the through holes 42 in the blocking portion from the inside out. At this time, access to the inner end of the through hole 42 is made possible by the recess 43. The outer surface of the locking portion 60 is sloped to allow the locking portion 60 to be received in the through hole 42, with the pin 56
is compressed as shown in FIG. Before the outer end 62 of the pin 56 reaches the outer end of the reserve space 52, the ear 5
The blind hole 55 of No. 4 is connected to the through hole 42 along the second axis.
is aligned to the axis of The pin 56 then has its head 5
8 is pushed in completely until it abuts the base 18.
In this position, the locking portion 60 passes through the outer end of the through hole 42 and expands into the reserve space 52 (FIG. 16). The inner end of the locking portion 60 is formed with square corners to retain the pin within the through hole 42, and a portion of the pin 56 adjacent the outer end 62 is formed with an adjacent ear 54.
The seat 16 is placed in the blind hole 55 at the base 18.
axially, but also allows rotation of the seat between the upper and lower positions.

Installation of the seat 16 is very quick and easy, but at the same time it cannot be easily removed. However, this does not pose a problem even during cleaning, as the seat can be easily reached even if it is in that location as long as the lid is removed. Also seat 1
6 to the base 18 is in a position that is not visible to the normal user.

A second embodiment 70 of the present invention is shown in FIG. 17 for situations in which it is desired to conceal the joint and at the same time allow easy removal of either the lid or the seat. In this embodiment, the hinge base 71 includes a base portion 75 and a carriage 76 . The two hinge axes 72 and 73 are oriented in opposite directions and aligned on a single axis. The hinge shaft 72 is fixed to a base portion 75, which, like the base portion 18, is secured to the rear of the toilet bowl with a nut (not shown).

The other hinge shaft 73 is formed integrally with the carriage 76. The carriage 76 has a beveled edge 74 that fits into a corresponding guideway 77 in the base body 75 and is dovetailed to the base body 75 . In this connection, the hinge axis 73 moves along the first axis and without rotating the hinge axis 73 and without moving the hinge axis 73 laterally (where lateral means radially relative to the hinge axis). Defined as pointing in the direction of a direction) capable of sliding. As in the first embodiment, the hinge axes 72 and 73 each have lugs 78 and 79 projecting radially from the hinge axes.

The toilet lid 80 has an integrally molded hinge element 82. Each hinge element 82 has a non-circular, keyhole-shaped through hole 84 consisting of a slot part and a circular part to receive one of the shafts 72 and 73 without significant play. Each of the through holes 84 extends from the insertion end 87 to the outer locking end 88. The lock end 88 continues into a reserve space 89 defined by a counterbore 90. The outer surface of counterbore 90 forms a bearing surface 91 .

Stool 92 has ears 93 adapted to clamp hinge element 82 . Each ear 93 has an inwardly opening blind hole 95 that is axially adapted to be aligned with the first axis.

When attaching the toilet lid 80 and the seat 92 to the base 71, the outside of the hinge element 82 is first clamped with the ears 93, and the through holes 84 and 95 are aligned along the first axis. Next, the angle of the slot of the through hole 84 on the right side (in FIG. 17) is aligned with the axis 7.
The assembly position is aligned with the lugs 78 of No. 2.
The right hinge element 87 and the ear 93 then rest on the shaft 72 and the insertion end 87 rests on the outer stop surface 9 of the base portion 75.
It is slid and inserted until it abuts 8. In this position the lug 78 is located in the reserve space 89 past the locking end 88. The outer side 101 of the shaft 72 also extends beyond the lug 78 and is received in the blind hole of the adjacent ear 93.

Next, the through hole 84 on the left side (in FIG. 17)
and 95 are aligned with axis 73 along the first axis. The angle of the slot of the left side through hole 84 is the same as the lug 79.
, the carriage 76 is slid into the guideway 77 and the shaft 73 is inserted into the through hole 84 until the outer surface 103 of the carriage 76 abuts the insertion end 87 (FIG. 26).
(Figure 25). The left hinge joint is
This is done in this position by inserting the lug 79 past the locking end 88 of the left hinge element 82 into the reserve space 89. Further, the left side hinge extension portion 93 of the outer end 105 of the shaft 73 extends into the blind hole 95 .

The butterfly program assembly is designed to fit the toilet lid 80 and the seat 92 when the lugs and corresponding slots are not in position for the right lug/slot pair as shown in FIG. 17 and for the left lug/slot pair as shown in FIG. are held on the base 71 in the axial direction. At the same time, the left hinge shaft 73 is locked axially, against rotation, and laterally relative to the toilet bowl. However, the lid 80 and the seat 92 can freely rotate around the hinge axis, either integrally or independently.

Although lugs 78 and 79 and the corresponding slots are shown as being all aligned with each other at the same angle in the preferred embodiment, this is not necessary.
However, each lug/slot pair must still be aligned at the same angle. It should be noted that the angular position for each pair need not be the same as for the other pairs. If they are not the same, the lid 80 must be rotated after the right lug/slot pair is assembled to align the left lug/slot pair.

Thus, the present invention provides a butterfly-shaped toilet cover member that is easy to assemble and disassemble for both the toilet lid and seat. Both the lid and the seat are securely connected, have little radial and axial loosening, and cannot be accidentally removed. Both joints are hidden from view to prevent tampering.

From the above description, various obvious modifications and changes can be made. For example, hinge shafts 72 and 73
may be slidably attached to the toilet lid 80 with respect to each other, and a stationary hinge element 82 may be secured to the toilet, with the ears of the seat clamping the hinge element. Also, in the second embodiment, the hinge element may be formed on the seat and the ears may be formed on the lid.
